Check out these dope bags from South 2 West 8. Handcrafted in the United States, they're a  favorite amongst the workwear heads at Nepenthes. Those people definitely know quality fabric and great construction. This is the kind of bag that gets more beautiful with age, thanks to the  Sunforger™ canvas.

The Sunforger™ canvas can stand up to the heaviest snow loads, high winds,and ice cover while remaining soft, breathable, and water repellent for years.
